In this article, we mainly introduce several factors in the maintenance of jaw crusher.

Jaw Crusher Maintenance

In order to make sure the high crushing efficiency, good shaped final products, low energy consumption and stable operation, we need to operate jaw crusher properly and maintain jaw crusher regularly. The maintenance of jaw crusher mainly contains lubrication, tightening, adjustment and cleanness of jaw crusher.


In the working process of jaw crusher, operators should lubricate the friction surfaces timely in order to ensure its long term stable running.
